DMRS Slot Settings

These values are active for each slot when the Parameter Calculation Mode is set to Manual.

When using multiple instruments as shown in the tree view, inaccurate test data may occur if a combination of the GUI and SCPI is used to set or modify the instrument and test parameters. The software will not reflect changes made outside of the GUI even with the use of the Update from Instrument button. For all tests, use only one method to configure the settings, GUI or SCPI.

When configuring multiple instruments with SCPI instead of using the GUI, the commands must be executed for each instrument.

When using multiple instruments as shown in the tree view, after clicking the State On button, all settings for this window gray out and cannot be changed. To change the settings, first click the State Off button.

Buttons

This button indicates that the current real-time settings have been applied to the instrument—no action is required. This button is not available when the Apply Needed button is active. When using multiple instruments as shown in the tree view, this button is not displayed.

This button displays in place of the Settings Current button. It indicates that the instrument settings are not currrent and need to be updated with the new software settings. Click this button to update the insturment's settings. This button shows in all windows regardless of where the change was made. When using multiple instruments as shown in the tree view, this button is not displayed.

DMRS Seq Index

Choices: 0 when RB ≤ to 5, 0 or 1 when RB > 5

Default: 0

Choices: Active when Parameter Calculation Mode is set to Manual.

Enter a value for the sequence index for the demodulation reference signal in each slot of the subframe (See 3GPP TS 36.211).

DMRS Grp Index

Range: 0 to 29

Default: 0

Choices: Active when Parameter Calculation Mode is set to Manual.

Enter a value for the group index for the demodulation reference signal in each slot of the subframe (See 3GPP TS 36.211). Sequence groups are typically used to multiplex reference signals in neighboring cells.

DMRS Cyc Shift

Range: 0 to 11, step 1

Default: 0

Choices: Active when Parameter Calculation Mode is set to Manual.

Enter a value for the cyclic shift for the demodulation reference signal in each slot of the subframe (See 3GPP TS 36.211). Cyclic shifts are used to multiplex reference signals from different terminals within a cell.
